If a particle moves in a circle describing equal angles in equal intervals of time, the velocity vector:
Correct answer: C. Changes in direction only
- A. Remains constant.
- B. Changes in magnitude only.
- C. Changes in direction only
- D. Changes both in magnitude and direction
Explanation
In circular motion, the direction of velocity changes at every point and it is along the tangent however, its magnitude remains constant.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
